Reaction time is one of the important methods to study a person's central information processing speed and coordinated peripheral movement response. Visual choice reaction time is a type of reaction time and is very important for drivers, pilots, security guards, and so forth. Previous studies were mainly on simple reaction time and there are very few studies on visual choice reaction time. The...
Number of Words: 3711 (includes title, abstract, body, references) List of Tables and Figures: Table 1. Selection of results from the Driving Experience Questionnaire. Kilometers/year and days/year were used to determine the driving experience category. Figure 1. Aerial-view schematic of a complex intersection. Changes could occur in the circled regions to the left, center or right of the inter...
Background and Objective: Road traffic injuries are among the most important causes of death and disability in Iran, and the country has one of the highest prevalence of opioid drug use, especially among drivers. The effect of different situations related to opioid use needs great attention. The purpose of this study was to estimate the effect of driving in the withdrawal phase on the occurrenc...
OBJECTIVE To evaluate sleep, alertness, salivary cortisol levels, and autonomic activity in the afternoon and morning shifts of a sample of short-distance bus drivers. METHODS A sample of 47 bus drivers was evaluated. Data regarding subjects and working characteristics, alertness (psychomotor vigilance task), sleep habits (Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Actigraphy),...
background aggregatibacter actinomycetemcomitans and tannerella forsythensis are two major pathogens in destructive periodontal disease in humans. the detection of these bacteria is needed for diagnosis and management of the mentioned diseases. objectives we aimed to develop and compare improved multiplex conventional and sybr green real time pcr assays for a specific diagnosis of the organisms...
In this paper, the stabilization strategies of a general nonlinear car-following model with reaction-time delay of the drivers are investigated. The reaction-time delay of the driver is time varying and bounded. By using the Lyapunov stability theory, the sufficient condition for the existence of the state feedback control strategy for the stability of the car-following model is given in the fo...
We investigated, using questionnaires, different strategies for removing drivers' overoptimism (Svenson et al., 2012a) about how fast their speed could be decreased when they were speeding compared with braking at the speed limit speed. Three different learning groups and a control group made collision speed judgments. The first learning group had the distance a car travels during a driver's re...
